I'm guessing from the way -yo is declined, that it is of neuter gender and falls within the second declension type, with accusative plural being N or G. However I prefer to get that confirmed by people who know more about this than I do.
Neuter gender.
Well... I don't remember formal grammar rules, so have no idea what declension type it is.

I guess, animate nouns should, as usual, use genitive as accusative plural, but I can't recall any animate -ё noun to prove that. Maybe, there is no one such noun.
The fact that most of the -ё nouns just has no plural forms:

Usual nouns; plural forms exist: остриё - острия, ружьё - ружья, цевьё - цевья, копьё - копья...
Collective nouns, no plural: бабьё, дубьё, зверьё, мужичьё, дурачьё, вороньё, комарьё, бельё, жильё, старьё, сырьё...
Verbal nouns, no plural: мытьё, нытьё, житьё, питьё, шитьё, быльё...
